TYPE-WRITER.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed September 14, 1904. Serial No. 224,435.

To all whom, it may concern.-

Be it known that I, JOHN ANDERSON RUF- FIN, a citizen of the UnitedStates, residing at New York city, New York, have invented certain newand useful Improvements in Type- Writers, of which the following is aspecification.

My invention relates to type-writers, and particularly to a supply orwinding roll for the material to be printed upon, the said winding-rollbeing arranged in appropriate relation to the paper-feed mechanism, sothat the operation of the said paper-feed mechanism will draw the paperor material to be printed upon from the said supply or winding roller.

I have shown the invention as embodied in the form of machine known asthe Hammond; but it will be understood that I do not wish to limitmyself in this respect.

The invention consists in the features and combination and arrangementof parts hereinafter described, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewthrough the paper holder or cylinder of a Hammond typewriter; and Fig. 2is a cross-sectional view through the said paper holder or cylinder,this View showing also a part of the printing mechanism and thepaper-feed rolls. Fig. 3 is a view of detent mechanism associated withthe winding-roll, and Fig. 4 is an end view of the winding-roll and itssupporting-bracket.

In a machine of the type known as the Hammond, in which the paper iscontained or coiled in a paper receptacle or cylinder forming part ofthe paper-carriage, difficulty is experienced when thick paper orcardboard is to be printed upon, owing to the fact that such material isso stiff as to resist proper coiling within the paper-cylinder whenmanipulated through the feed-rolls in the ordinary manner. I have soughtto provide means for overcoming this difficulty in this type ofmachine,and with this end in View I arrange within the paper holder or cylindera winding or supply roller adapted to receive the end of the cardboardor stifi' paper when it is inserted between the feed-rolls, so that bytu rning the winding or supply roller the paper or cardboard will bewound upon the said roller and drawn down between the ordinary feedrollsuntil the proper point on, the said paper arrives at the printing-point,and then when the feed-rolls are operated to raise the paper for theline-spacing the said paper will be drawn from the supply-roll, whichlatter turns step by step as the line-spacing actions occur.

In the drawings, 1 represents the end frames of the paper holder orcylinder of a Hammond type-writer, these frames having between them acage 2, preferably formed of wire-netting and of substantiallycylindrical shape and constituting the paper-holder proper. Thefeed-rolls are arranged, as ordinarily, at 3 3 at the top of thepaper-cylinder and when turned raise the paper step by step to presentdifferent portions to the printing-point between the shuttle 4 and thehammer 5. Within the paper-cylinder I arrange the supply or windingroller 6, Which is journaled centrally in the said cylinder, thebearings for the roller being provided by brackets or arms 7 attached tothe outer side of the end frames by means of pins 8 on the end framesentering openings in the brackets and thumb-screws 9 passing through thebrackets into the end frames. The winding or supply roller may be turnedat will by a handle or finger-button 10 on the end of its shaft 11. Thewinding-roller is provided with a deep groove 12 extendinglongitudinally thereof and having a flaring upper portion or mouth at13. This is normally presented upwardly, as shown in Fig. 2, and whenthe feed-rolls 3 are separated and the paper dropped between them, as inordinary practice, its lower edge will be received by the deep groove12, and then by turning the winding-roller the paper or cardboard willbe wound thereon, as indicated in Fig. 2, and drawn down into positionbetween the parts of the printing mechanism. The paper will thus becoiled or wound within the paperreceptacle and is drawn therefrom, as inordinary practice, by the successive operations of the feed-rolls 3 3,and during these feeding actions the winding or supply roll will rotatestep by step as the feeding actions occur.

In order to center the winding-roll so that the flaring mouth 13 will benormally presented upwardly, I provide a detent, consisting of a pin 14,having a conical end adapted to enter a conical recess in one of thebrackets 7, the said pin passing through the end plate 15 of the windingor supply roll and being headed at 16 on its inner end to bear on theinner side of the said end plate and limit its cylinder, feed-rolls atthe top thereof, a windoutward movement. The pin is pressed by a spring17, arranged in a socket 18, formed in the winding-roller. The relationof the parts is such that when the detent is engaging a recess in thebracket 7 the flaring mouth 13 will be directed upwardly to receive thelower edge of the paper. While the detent is sufliciently strong in itsaction to hold the supplyroller, it will yield freely when the paper isfed upwardly by the feed-rolls. By means of this detent the operator canreadily determine when the winding-roll is properly set, the pressure orforce necessary to turn the button 10 being slightly greater when thedetent is in action or is engaging the recess in the bracket 7 than whenit is free therefrom.

I prefer to make the winding roller of wood, with the end plates 15 ofmetal and screwed thereto.

I may also utilize'the winding-roller as a means of providing a seriesof stops'or rests for cards'of different sizes, and for this purpose thesaid roller is provided with a series of slots or grooves 16 These areof different depths and provide means for supporting cards of differentsizes when brought beneath the opening between the feed-rollers. The

winding-roll may be set rigidly in position topresent any one of theseries of grooves in line with the feed-rollers by means of a thumbnut19, engaging a screw-threaded pin or journal 20, extending from one ofthe end plates or heads 15, as shown at Fig. 1.

I claim as my invention 1. In combination in a type-writer, apapercylinder', feed-rolls at the top thereof and a winding and supplyroll arranged within the cylinder having means to automatically graspthe paper and wind the same when the roll is turned, substantially asdescribed.

2. In combination in a type-writer, a papercylinder, feed-rolls at thetop thereof and a winding and supply roll arranged within the cylinderhaving means to automatically grasp the paper and wind the same when theroll is turned, said means consisting of a groove to receive the edge ofthe paper, substantially as described.

3. In combination in a type-writer, a papering-roll within the cylinder,having means to automatically grasp the paper and wind the same when theroll is turned, and detent means for holding the roll with saidautomatic means in position to grasp the paper, said detent means beingadapted to be overcome by the feeding action of the feed-rolls,substantially as described.

4:. In combination, a paper-receptacle, a winding-roller therein,brackets in which the said roller is journaled, said brackets beingsecured to a part of the paper-receptacle, and a detent between theroller and one of the brackets, said roller with its brackets and detentbeing removable as one body substantially as described.

5. In combination, in a type-writer, a roller having a plurality ofrests or supports at different heights to receive the paper and printingmechanism, substantially as described.

6. In combination, with printing mechanism, a roller having a pluralityof grooves of different depths to receive and. support the paper,substantially as described.

7. In combination, with printing mechanism, a roller having a pluralityof supports of different heights, and means for holding the said rollerin any position to which it may be adjusted, substantially as described.

8. In combination, with printing mechanism, a roller having a pluralityof supports of different heights, and means for holding the said rollerin any position to which it may be adjusted, said means consisting'of aclampnut, substantially as described.

9. In combination in a type-writer, a papercylinder, a winding-rollertherein, having a rest for the lower edge of the paper and means forgrasping the paper and winding the same when the roller is turned, andfeed-rolls associated with the paper-cylinder for unwinding the paperfrom the winding-roller substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN ANDERSON RUFFIN.
